[0001] The utility model relates to the technical field of desulfurization, in particular to a desulfurization agent negative pressure self-priming dosing device. Background Art

[0002] The float glass process is a major method for producing flat glass. This method uses the surface tension of the metal tin to form the glass into a flat plate by pouring molten glass on the surface of a tin bath. During the production of float glass, impurities in the molten glass, especially sulfides, will have a negative impact on the quality of the glass. Sulfides can cause defects such as bubbles and discoloration in the glass, affecting the transparency and optical properties of the glass.

[0024] According to an embodiment of the utility model, a desulfurizing agent negative pressure self-priming dosing device is provided.

[0025] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4As shown, the desulfurizer negative pressure self-priming dosing device according to the embodiment of the utility model comprises a connecting pipe 1, both ends of the connecting pipe 1 are provided with negative pressure ventilation flue 2, and one end of the negative pressure ventilation flue 2 is provided with an induced draft fan, and the induced draft fan draws smoke to reduce the pressure inside the negative pressure ventilation flue 2, and the connection point of the induced draft fan is usually located at a certain position of the flue system, so that the negative pressure ventilation flue 2 forms a negative pressure environment, and the middle top of the connecting pipe 1 is provided with a desulfurizer outlet pipe 3, and the top of the desulfurizer outlet pipe 3 is provided with a dosing amount control component 4; the dosing amount A desulfurizer inlet pipe 5 is arranged at the top of the control component 4, and a desulfurizer silo 6 is arranged at the top of the desulfurizer inlet pipe 5; a support frame 7 is sleeved on the outer side of the negative pressure ventilation flue 2, and a dosing stabilization mechanism 8 is arranged on the top of the support frame 7, and the dosing stabilization mechanism 8 is connected to the end of the dosing control component 4; in order to keep the support frame 7 stable, a first support plate 9 is arranged at the bottom end of the support frame 7, and a plurality of mounting holes 10 are arranged in the first support plate 9, and the support frame 7 is connected to the fixed surface through the mounting holes 10, so that the support frame 7 is kept stable.

[0026] With the aid of the above scheme, the desulfurizer dosing method of the utility model is changed from relying on the positive pressure delivery of the Roots blower to relying on the negative pressure self-absorption of the agent by the flue itself. The desulfurizer is directly vertically sucked into the flue by negative pressure to react, which overcomes the problem of easy blockage at the bends of the original fan positive pressure delivery and the problem of unfavorable desulfurizer feeding, and saves a conveying fan with a power of 22 kilowatts, does not require external force load, and has a certain energy-saving effect.

[0027] In one embodiment, for the above-mentioned dosage control component 4, the dosage control component 4 includes a drug delivery cavity 401 arranged at the top of the desulfurizer outlet pipe 3, a rotating block 402 is arranged inside the drug delivery cavity 401, and a plurality of drug grooves 403 are arranged on the circumferential side wall of the rotating block 402. At the same time, openings are arranged at both the upper and lower ends of the drug delivery cavity 401 for connecting with the desulfurizer outlet pipe 3 and the desulfurizer inlet pipe 5; a motor 404 is arranged on the outer wall of the drug delivery cavity 401, and the motor 404 is connected to an external control panel, and the start and stop and speed of the motor 404 are controlled by the control panel, and the output shaft of the motor 404 extends to the inside of the drug delivery cavity 401 and is connected to the center position of the rotating block 402, so that the rotating block 402 and the drug groove 403 can rotate, and the drug groove 403 delivers a fixed amount of desulfurizer within a certain period of time at a set speed, thereby realizing accurate dosage control.

[0028] The working principle of the dosing amount control component 4 is as follows: the rotating block 402 is driven to rotate by the motor 404, and a plurality of medicine grooves 403 are arranged around the rotating block 402. When the motor 404 is started, the rotating block 402 starts to rotate, and the medicine grooves 403 move accordingly. Since the medicine grooves 403 are designed as grooves of fixed volume, they can deliver the desulfurizer from the desulfurizer silo 6 through the desulfurizer inlet pipe 5 to the medicine delivery cavity 401 at a certain periodicity according to the preset speed and time interval during the rotation process, and then discharge it to the connecting pipe 1 through the desulfurizer outlet pipe 3.

[0029] In one embodiment, for the above-mentioned drug dosing stabilization mechanism 8, the drug dosing stabilization mechanism 8 includes a second support plate 801 arranged at the top of the support frame 7, a slide groove 802 is arranged in the middle of the second support plate 801, a slider 803 is arranged in the slide groove 802, and a clamping plate 804 is arranged at the top of the slider 803; the clamping plate 804 is an arc-shaped structure at one end close to the drug delivery cavity 401, and a cushion 805 is arranged between the drug delivery cavity 401 and the clamping plate 804; the drug dosing stabilization mechanism 8 includes a fixing plate 806 arranged at one end of the slide groove 802 away from the drug delivery cavity 401, a bolt 807 is transversely arranged in the fixing plate 806, and one end of the bolt 807 is connected to the slider 803, so as to improve the stability of the drug dosing amount control component 4 during operation, improve the stability of drug dosing, and can conveniently adjust the position of the clamping plate 804 to ensure the appropriate contact pressure between the drug dosing stabilization mechanism 8 and the drug delivery cavity 401.

[0030] The working principle of the drug addition stabilization mechanism 8 is as follows: the clamping plate 804 is close to the drug delivery cavity 401 through an arc-shaped structure. The soft cushion 805 is located between the drug delivery cavity 401 and the clamping plate 804, which plays a role in shock absorption and protection. By adjusting the bolt 807 against the slider 803, it is ensured that the drug addition stabilization mechanism 8 applies a certain pressure to the drug delivery cavity 401, thereby maintaining the stability of the entire drug addition amount control assembly 4.

[0031] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0032] In actual application, the desulfurizer in the desulfurizer silo 6 enters the dosing control component 4 through the desulfurizer inlet pipe 5 and is discharged through the desulfurizer outlet pipe 3. Due to the negative pressure inside the negative pressure ventilation flue 2, the desulfurizer is self-absorbed and vertically sucked into the connecting pipe 1, and then enters the flue to react with the sulfide in the flue gas to achieve desulfurization.

[0033] In addition, the desulfurizer negative pressure self-priming dosing device of the utility model can not only be used for dosing of desulfurizers, but also can be used for dosing of other types of powdered or granular agents, especially in situations where chemical reaction with flue gas or other gaseous media is required. According to the dosing requirements of different agents, the parameters of the dosing control component 4 are adjusted to ensure the accuracy of dosing.

[0034] In summary, the desulfurizer dosing method of the utility model is changed from relying on the positive pressure delivery of the Roots blower to relying on the flue's own negative pressure to self-absorb the agent. The desulfurizer is directly vertically sucked into the flue by negative pressure to react, which overcomes the problem of easy blockage at the bend of the original fan positive pressure delivery and the problem of unfavorable desulfurizer feeding. By setting the dosage control component 4, the rotating block 402 and the medicine groove 403 can rotate, and the medicine groove 403 delivers a fixed amount of desulfurizer within a certain period of time at a set speed, thereby achieving accurate dosage control. By setting the dosage stabilizing mechanism 8, the stability of the dosage control component 4 during operation can be improved, the stability of the dosage can be improved, and the position of the clamping plate 804 can be easily adjusted to ensure the appropriate contact pressure between the dosage stabilizing mechanism 8 and the agent delivery cavity 401.
